 significant bits of the start offset of the Offset logical resource units for BR header. LSB of Resource Start These are the least significant bits of the start offset of the Offset logical resource units for BR header. HARQ Feedback Allocation This field is start offset of HARQ feedback allocation. Start Offset Allocation Size Resource size for each BR header (1 or 2 logical resource units). Long TTI Indicator Indicates number of subframes spanned by the allocated resource for BR header: Obo 1 subframe (default); Ob1 4 UL subframes for FDD or all UL subframes for TDD. Number of Received The number of BR preamble sequence indices included in this Preamble Sequences ACK A-MAP IE (1, 2, 3, 4). Preamble Sequence Index Preamble sequence index received in the BR opportunity. Message Decoding Indicate the decoding status of quick access message: Indicator Obo Message not decoded; Ob1 Message decoded corresponding to preamble sequence index. Grant Indicator To indicate whether grant of BR header for the BR preamble sequence index is included. If this bit is set, the UL resource is allocated. The Broadcast Assignment A-MAP IE is used to allocate resources for a broadcast burst. A broadcast burst contains one or more broadcast MAC control messages. Table 10-15 describes the parameters of the broadcast assignment information element. An example of usage of the Broadcast Assignment A-MAP IE for indications of traffic, paging, or neighbor advertisement messages is shown in Figure 10-11. Note that if this information element exists in a control region, it will be the first assignment A-MAP immediately following the non-user-specific A-MAP. The broadcast burst signaled by the Broadcast Assignment A-MAP IE is always transmitted using an SFBC transmit diversity scheme and QPSK as the modulation scheme. The periodicity of the time- domain repetition is one frame. During the time interval where a broadcast burst is repeated, other broadcast bursts can only be transmitted without time-domain repetition. For each broadcast burst tr
