Computer-aided mapping of system information medium access control protocol messages

1. A method to transmit system information from a base station in a radio access network, comprising:

receiving data packets over a broadcast control channel (BCCH);

generating first system information blocks from the data packets, the first system information blocks comprising a system frame number, a public land mobile network identity, and a cell identity, wherein one or more of the first system information blocks indicate how a system information message is to be transmitted;

scheduling the first system information blocks for transmission using a fixed schedule;

generating second system information blocks from the data packets;

scheduling the second system information blocks, using dynamic scheduling, for transmission in the system information message;

mapping a first system information block in the first system information blocks to a broadcast channel;

mapping the system information message to another channel; and

transmitting, by the base station, the first system information block and the system information message.

2. The method of claim 1 , further comprising using Orthogonal Frequency Division Multiple Access to transmit the first system information blocks and the system information message.

3. The method of claim 1 , wherein the second information blocks comprise cell re-selection information.

4. The method of claim 1 , wherein the first system information blocks and the second system information blocks are received from the BCCH by a medium access control (MAC) layer.

5. The method of claim 1 , further comprising scheduling each system information block based on a corresponding type of data packet received over the BCCH.

6. The method of claim 1 , wherein data packets for the second system information blocks are received more often than data packets for the first system information blocks.

7. The method of claim 1 , further comprising indicating a frequency band, in the first system information blocks, used to transmit the system information message.

8. A base station, comprising:

a medium access control unit to receive data packets from a radio link control (RLC) protocol layer and to generate system information blocks and a system information message from the data packets, wherein at least one of the system information blocks comprises a statement to indicate how the system information message is to be transmitted, and wherein the system information blocks are to be scheduled for transmission using a fixed schedule, and the system information message is to be scheduled dynamically using available subcarriers and one or more transmission time intervals for an Orthogonal Frequency Division Multiple Access (OFDMA) transmission; and

a transmitter to transmit the one or more system information blocks and the system information message.

9. The base station of claim 8 , further comprising receiving the data packets over a broadcast control channel (BCCH).

10. The base station of claim 8 , wherein the system information blocks comprise a master information block (MIB) and a system information block type 1 (SIB 1).

11. The base station of claim 10 , wherein the MIB is mapped to a broadcast channel (BCH).

12. The base station of claim 8 , wherein the medium access control unit comprises a processor.

13. The base station of claim 8 , wherein the system information blocks comprise a system frame number, a public land mobile network identity, and a cell identity.

14. The base station of claim 10 , wherein the statement is contained in the SIB 1.

15. One or more non-transitory computer-readable media comprising instructions to form one or more medium access control protocol messages, the instructions to cause a computing device, upon execution of the instructions by one or more processors of the computing device, to:

generate system information blocks including a master information block (MIB), from data packets received over a logical channel, wherein a first system information block indicates how a system information message is to be transmitted;

schedule the MIB and the first system information block for transmission using a fixed schedule;

generate second system information blocks from the data packets;

schedule the second system information blocks, using dynamic scheduling, for transmission in the system information message;

map the MIB to a broadcast channel; and

map the first system information block and the system information message to another channel for transmission.

16. The one or more non-transitory computer-readable media of claim 15 , wherein the data packets are received over the logical channel from a radio link control layer.

17. The one or more non-transitory computer-readable media of claim 15 , wherein the first system information block is a system information block type 1 (SIB 1).

18. The one or more non-transitory computer-readable media of claim 15 , wherein the second system information blocks comprise a system information block type 3 (SIB 3) that includes cell reselection information.

19. The one or more non-transitory computer-readable media of claim 15 , wherein the instructions are further to the system information blocks onto a plurality of transport channels.

20. The one or more non-transitory computer-readable media of claim 15 , wherein data packets for the second system information blocks are received more often than data packets for the first system information block.
