QPSK 1/8 and Group 2 using QPSK 1/2, the lookup tables shown in Table 10-2 can be generated iteratively using the following equations for all values of Ntotal and k [2]: k = 0, N total < 27 Ntotal < 32 (10-3) = 0, 1, 2, 3, 4, 33 Ntotal < 48 G2(I) Ntotal 4G1 (I) I = Ib(Ntotal) Ntotal = 0 Ib(Ntotal) 1) (Ntotal < Ntotal < 25 (10-4) (Ntotal 1) +6 < N total < 28 (Ntotal + 7 29 < N otal S 48 otherwise The HARQ feedback A-MAP consists of HARQ feedback IEs to acknowledge success or failure of uplink data transmission. Each HARQ feedback A-MAP IE carries one bit of information which is then repeated eight times. The resulting bits are scrambled by the eight least significant bits of the Station Identifier (STID) of the MS assigned during network entry. Depending on the channel conditions, a certain amount of power boosting may be applied to each scrambled bit sequence.
