This paper introduces a multi-cell transmission
scheme for High-Speed Downlink Packet Access (HSDPA) networks,
called Multiflow. In this concept, downlink data is
transmitted to a user terminal at the border of two cells from
one or both of the cells. The cells may belong to same NodeB
or to two different NodeBs. The data flows are separated by
different scrambling codes used by each associated cell, thus
the flows can be treated independently. This provides increased
multi-user diversity by means of flexibility in downlink resource
management, in addition to the spatial diversity of multiple
transmission locations. Another important gain mechanism for
this scheme is realized by short-term load balancing between
neighboring cells. We evaluate the performance of Multiflow by
semi-static system level simulations. The presented results reveal
high throughput gains for users in handover areas and also a
slight improvement to overall network performance.
