The effect of F-DPCH on VoIP over HSDPA Capacity

In WCDMA Rel. 5 HSDPA the fraction of the base station power used for signalling channel overhead is relatively large for low bit-rate services such as VoIP. Examples of such overhead are the high speed shared control channel (HS-SCCH) and the associated dedicated channel (A-DPCH). One remedy is the...

Zusammenfassung:In WCDMA Rel. 5 HSDPA the fraction of the base station power used for signalling channel overhead is relatively large for low bit-rate services such as VoIP. Examples of such overhead are the high speed shared control channel (HS-SCCH) and the associated dedicated channel (A-DPCH). One remedy is the suggestion of using a fractional dedicated channel (F-DPCH) instead of A-DPCH. In this paper we investigate the impact of power overhead for a system with only VoIP users. The capacity is compared both theoretically and through dynamic radio network simulations. Theoretical and simulated results both show a capacity increase of around 15% when A-DPCH is exchanged by F-DPCH
