A user equipment can establish a radio resource control connection with a wireless wide area network base station to enter a radio resource control connected state. The user equipment can send a medium access control control element requesting system information while in the radio resource control connected state. ## Claims ### Claim 1 A method comprising: establishing, by a user equipment, a radio resource control connection with a wireless wide area network base station to enter a radio resource control connected state; and sending, by the user equipment, a medium access control control element requesting system information while in the radio resource control connected state, wherein the medium access control control element contains a bitmap for requesting system information blocks for the system information. ### Claim 2 (depends on 1) The method according to claim 1, wherein the medium access control control element requesting system information provides for a random access channel procedure for requesting an uplink grant. ### Claim 3 (depends on 1) The method according to claim 1, wherein a length of the bitmap is at least long enough to request remaining system information blocks in a wireless wide area network beyond default system information blocks provided by the wireless wide area network. ### Claim 4 (depends on 1) The method according to claim 1, wherein each bit of the bitmap corresponds to one system information block. ### Claim 5 (depends on 4) The method according to claim 4, wherein each bit of the bitmap corresponds to at least one selected from a system information message based on scheduling information and a system information block. ### Claim 6 (depends on 1) The method according to claim 1, wherein the bitmap includes extra bits reserved for information that is not currently available at the time of sending the medium access control control element. ### Claim 7 (depends on 6) The method according to claim 6, wherein the bitmap includes extra bits reserved for system information blocks that are not currently available at the time of sending the medium access control control element. ### Claim 8 (depends on 1) The method according to claim 1, wherein the bitmap includes a bit that indicates an additional bitmap is available for additional system information blocks. ### Claim 9 An apparatus comprising: a controller that controls operations of the apparatus, where the controller establishes a radio resource control connection with a wireless wide area network base station to enter a radio resource control connected state; and a transceiver coupled to the controller, where the transceiver sends a medium access control control element requesting system information while in the radio resource control connected state, wherein the medium access control control element contains a bitmap for requesting system information blocks for the system information. ### Claim 10 (depends on 9) The apparatus according to claim 9, wherein the medium access control control element requesting system information provides for a random access channel procedure for requesting an uplink grant. ### Claim 11 (depends on 9) The apparatus according to claim 9, wherein a length of the bitmap is at least long enough to request remaining system information blocks in a wireless wide area network beyond default system information blocks provided by the wireless wide area network. ### Claim 12 (depends on 9) The apparatus according to claim 9, wherein each bit of the bitmap corresponds to one system information block. ### Claim 13 (depends on 12) The apparatus according to claim 12, wherein each bit of the bitmap corresponds to at least one selected from a system information message based on scheduling information and a system information block. ### Claim 14 (depends on 9) The apparatus according to claim 9, wherein the bitmap includes extra bits reserved for information that is not currently available at the time of sending the medium access control control element. ### Claim 15 (depends on 14) The apparatus according to claim 14, wherein the bitmap includes extra bits reserved for system information blocks that are not currently available at the time of sending the medium access control control element. ### Claim 16 (depends on 9) The apparatus according to claim 9, wherein the bitmap includes a bit that indicates an additional bitmap is available for additional system information blocks. ### Claim 17 (depends on 9) The apparatus according to claim 9, wherein the apparatus comprises a smartphone. ### Claim 18 A method comprising: establishing, by a user equipment, a radio resource control connection with a wireless wide area network base station to enter a radio resource control connected state; and sending, by the user equipment, a medium access control control element requesting system information while in the radio resource control connected state, wherein the medium access control control element provides for a random access channel procedure for requesting an uplink grant, and wherein the medium access control control element contains a bitmap for requesting system information blocks for the system information.
