eters [2] Parameter (Bits) Description A-MAP IE Type UL Persistent Allocation A-MAP IE. Allocation Period Period of persistent allocation: Ob00 de-allocation of persistent resource; 0b01 2 frames; 0b10 4 frames; Ob11 8 frames. Resource Index Confirmation of the resource index for a previously assigned persistent resource which has been de-allocated (Resource index includes location and allocation size): 5 MHz 0 in 2 most significant bits + 9 bits for resource index; 10 MHz 11 bits for resource index; 20 MHz 11 bits for resource index. Long TTI Indicator Indicates number of subframes spanned by the allocated resource: Obo 1 subframe (default); Ob1 4 DL subframes for FDD or all DL subframes for TDD. HARQ Feedback Index for HARQ Feedback Allocation to acknowledge receipt of de- Allocation allocation A-MAP IE. SizeOffset Offset used to compute burst size index. Number of streams in transmission where up to 2 streams per MS supported: Obo 1 stream; Ob1 2 streams. Total Number of Total number of streams in the LRU for CSM (2,3,4 streams). Streams First pilot index for CSM with TNS = 2 streams: 0b00; 0b01. First pilot index for CSM with TNS = 3,4 streams: 0b00; 0b01; 0b10; Ob11. MIMO Encoder MIMO encoder format: Format Obo SFBC; Ob1 Vertical encoding. Precoding Flag Precoding flag: Obo Non-adaptive precoding; Ob1 Adaptive precoding using the precoder of rank Ns based on user's choice. N_ACID Number of ACIDs for implicit cycling of HARQ channel identifier (2,3,4,8). Initial_ACID Initial value of HARQ channel identifier for implicit cycling of HARQ channel identifiers. Allocation ObO Allocation in the first UL subframe relevant to an A-MAP region; Relevance Ob1 Allocation in the second UL subframe relevant to an A-MAP region.
