1 S o"eThe present document describes the 7T -& functions by means of si nallin procedure e'amples (Messa e !eJuence0harts). The si nallin procedure e'amples show the interaction between the 72, the different 7T -& nodes and the

0& to perform system functions. This ives an overall understandin of how the 7T -& wor"s in e'ample scenarios.

/.1D.3 S it #i% ro e!!C4 : to e!!C'$ : State%n the this scenario the ! &0 needs to et the 0C &T% from 5 &0 to be able to indicate to the 72 a new 0C &T% andwhich cell it is valid in ( iven by the Primary !cramblin 0ode).

The ! &0 also needs to et either

. information in the -0@ andBor 4-0@ to be used (if the 5 &0 selects -0@ andBor 4-0@ in a different waythan the 72 would do based on broadcast information) includin 7ser Plane flow control information for the %ur4-0@ 4P.

*. 7ser Plane flow control information for the 4-0@ (!econdary 00P0@) that the 72 selects if no !econdary00P0@ information is provide to the 72 in the 0 Physical 0hannel econfi uration messa e

%f receivin the 0C%5 the 5 &0 shall allocate a 0C &T% and provide it to ether with the Primary 0P%0@ information tothe ! &0. 4urther more, if the 5 &0 would li"e to select another -0@ andBor 4-0@ than the 72 would select

based on the broadcast information the 5 &0 also provides information on the 5 &0 !elected -0@ andBor 4-0@(alternative ). %f the 5 &0 does not select any 4-0@ the 5 &0 shall provide the user plane flow control information(alternative *).

The above solution would result in the followin seJuence
