  1. 16m Downlink Superframe Structure [1] [1]. IEEE C80216m-08_118r1

  2. Downlink Control Information Hierarchy

  3. Example of DL Super-frame Header • SCH for initial network acquisition, with fixed CP length to minimize blind detection • PSC for timing and frequency correction • Possible for SFN transmission within network • SSC for Cell_ID • P-BCH for network-wide common and static parameters such as bandwidth, CP length, superframe index, TDD ratio • Possible for SFN transmission within network • S-BCH for sector-specific parameters such as antenna setting, power setting, control zone setting, resource allocation setting, System Information message setting, 16e/16m ratio/offset, H-FDD setting, etc. • Sufficient to allow MS to decode the DL data channels • QPCH for quick paging messages • Possible with SFN transmission within QPCH zone

  4. Data Mini-frame Control Information • The control information relating to the data traffic in each data Mini-frame includes • Scheduling grant message for DL/UL resource allocation • System acquisition grant message for fast response to random access attempts • UL power control bits • ACK/NACK bits for UL data channel HARQ • We provide more details of two control structures of the data mini-frame in contributions IEEE C80216m-08/211 and IEEE C80216m-08/212, respectively.

  5. Example of Control Messages Carried on Data Channels • Common/broadcast control messages • using fixed periodical broadcasting without a dynamic scheduling grant message; and/or using a dynamic allocation of a data channel that is identified with a common MACID in the scheduling grant message • for example, additional downlink system parameter messages, uplink system parameter messages, full paging messages, etc. • User-specific control messages • Identified with user-specific MACID

  6. Text Proposal Insert the following text into Physical Layer sub-clause (C802.16m-08/003) 11.X Downlink Control Information Hierarchy 11.X.1 Super-frame header The Super-frame Header shall provides: • Synch signals for timing and frequency correction • Cell_ID • network-wide common parameters, e.g. bandwidth, CP length, superframe index, TDD ratio, etc. • with SFN transmission within the network • sector-specific system parameters that are sufficient for the MS to decode the DL data channels, e.g. antenna setting, power setting, control zone setting, resource allocation setting, System Information message setting, 16e/16m ratio/offset, H-FDD setting, etc. • Additional DL system parameters and UL system parameters are broadcasted in System Information message using the data channels • quick paging messages, possibly with SFN transmission within the quick paging zone • Full paging message transmitted using the data channels, possibly with SFN transmission within the paging zone

  7. Text Proposal Insert the following text into Physical Layer sub-clause: 11.X.2 Data Mini-frame Control Information The control information relating to the data traffic in each data Mini-frame includes: • Scheduling grant message for DL/UL resource allocation • System acquisition grant message for fast response to random access attempts • UL power control bits • ACK/NACK bits for UL data channel HARQ 11.X.3 Control Messages Carried on the Data Channel Additional downlink and uplink system parameter messages and full paging messages can be carried on the data channel using fixed periodical broadcasting without a dynamic scheduling grant message; and/or using a dynamic allocation of a data channel that is identified with a common MACID in the scheduling grant message. User-specific control messages can also be carried on the data channels using user-specific MACID.
