+
+            The RR entity of the mobile station initiates the immediate
+            assignment procedure by scheduling the sending on the
+            RACH and leaving idle mode.
+
+            It then sends maximally M + 1 CHANNEL REQUEST messages on
+            the RACH in a way such that:
+
+            - the number of slots belonging to the mobile station's RACH
+            between initiation of the immediate assignment procedure and
+            the first CHANNEL REQUEST message (excluding the slot containing
+            the message itself) is a random value drawn randomly for each
+            new initial assignment initiation with uniform probability
+            distribution in the set {0, 1, ..., max (T,8) - 1};
+
+            - the number of slots belonging to the mobile station's RACH
+            between two successive CHANNEL REQUEST messages (excluding
+            the slots containing the messages themselves) is a random value
+            drawn randomly for each new transmission with uniform probability
+            distribution in the set {S, S + 1, ..., S + T - 1};
+
+            Here, T is the value of the parameter "Tx-integer" broadcast on the BCCH;
+
+            M is the value of the parameter "max retrans" broadcast on the BCCH;
+
+            S is a parameter depending on the CCCH configuration and on the value
+            of Tx-integer as defined in table 3.1/GSM 04.08.
