This work was triggered by the UID_390032 Study on Dual-Cell HSDPA (withdrawn TR 25.825 v100).

HSPA features are successfully deployed in many networks. HSPA based mobile internet offerings are very popular and data usage is rapidly increasing.

The peak user throughout has been significantly enhanced as part of Rel-7 (MIMO, Higher Order Modulation). Even better and more consistent user experience across the cell and in particular in the outer cell coverage area is desired.

Deployment of additional network resources, such as a second HSPA carrier, creates an opportunity for network resource pooling as a way to enhance the user experience, in particular when the radio conditions are such that existing techniques (e.g. MIMO) can not be used.

The "Study on Dual-Cell HSDPA operation" revealed feasibility, benefits and complexity of combining network radio resources (i.e. cells on adjacent carriers) to address the operators’ desire for enhanced user experience and enhanced user experience consistency.

This work specifies dual-cell HSDPA operation for the following scenarios:

  • dual cell transmission only applies to HSDPA physical channels

  • two cells belong to the same Node-B and are on adjacent carriers

  • two cells do not use MIMO to serve UEs configured for dual cell operation

  • two cells operate in the same frequency band
