Setting a different bwp earlier in a connection establishment process to a wireless network by a ue when transitioning from an idle or inactive state

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 smaller 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 smaller 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.

An apparatus comprising:

• a processor;
• and
• a memory comprising computer-executable instructions that, when executed by the processor, cause the apparatus to perform the following operations:
• receiving, 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 apparatus during a connection establishment procedure to connect the apparatus to the wireless network, wherein the at least one selected bandwidth part is smaller than the initial bandwidth part, wherein the at least one selected bandwidth part is received via paging or system information after the apparatus transitions to idle/inactive state, or in a release message prior to the apparatus transition to the idle/inactive state, the smaller bandwidth part is utilized for an msg3 message of random access procedure;
• and
• sending, toward the network node, the msg3 message for connection establishment to the wireless network using the selected bandwidth part.
