25.4673GPPRelease 17Stage 2TSUTRAN architecture for 3G Home Node B (HNB)

In some HNB deployments the limited number of PSCs available to be allocated to HNBs may cause PSC ambiguity. This may result in the inability of identifying, at the source macro RNC, a unique target HNB corresponding to a PSC reported by a Legacy UE (i.e., UEs not capable of SI acquisition).

In this informative annex two solutions for PSC disambiguation are described.

The implementation options described in this Annex are not intended to be evolved in the 3GPP specifications.
