Method and apparatus for receiving system information

A base station (BS) for providing system information (SI), the BS comprising:

• one or more non-transitory computer-readable media having computer-executable instructions embodied thereon;
• and
• at least one processor coupled to the one or more non-transitory computer-readable media, and configured to execute the computer-executable instructions to:
• broadcast a system information block type 1 (SIB1) associated with a cell;
• receive, from a user equipment (UE), a first message including a common control channel (CCCH) service data unit (SDU), the CCCH SDU including a radio resource control (RRC) SI request message;
• and
• transmit, to the UE, a medium access control (MAC) control element (CE) including a UE contention resolution identity that matches a portion of the CCCH SDU, wherein:
• the MAC CE enables a MAC entity of the UE to indicate reception of an acknowledgment for the RRC SI request message to an RRC entity of the UE, and
• the SIB1 does not include information related to a Random Access (RA) resource specific to SI requested by the RRC SI request message.
