K value information: x _{kv, 1}, x _{kv, 2}..., x _{kv, 5}, x _{kv, 6};

Wherein, K value information x _{kv, 1}, x _{kv, 2}..., x _{kv, 5}, x _{kv, 6}be specially the index value of the first ratio K after quantification, search corresponding K value information concordance list according to this index value and can obtain the first ratio K after the quantification corresponding with this index value.

Such as, or be 6 bits for this length being used to indicate the field of K value information, then see table 2, K value information concordance list specifically can be as follows:

Table 2:

Visible, altogether can represent the first ratio K after 64 kinds of different quantifications.After subscriber equipment receives K value information from S-E-AGCH channel, can according to this K value information look-up table 2, the first ratio K after being quantized accordingly.Such as, if the K value information received is 000001, then known according to table 2, the first ratio K after quantification is K ₁; Again such as, if the K value information received is 000010, then known according to table 2, the first ratio K after quantification is K ₂, by that analogy.

Wherein, the coded system of this S-E-AGCH channel is identical with E-AGCH channel, specifically see prior art, can not repeat them here.
