—WCDMA based third generation networks are widely deployed and 3GPP is constantly seeking to evolve their performance. It is a well-known problem that reception quality degrades at cell edges. Multipoint transmission from two separate cells can be used to overcome this problem in single frequency deployments. In this paper we make an overview of several(More)
This paper studies how the performance of <i>Voice over IP (VoIP) over High Speed Downlink Packet Access (HS-DPA)</i> networks is affected if transmission to a <i>User Equipment (UE)</i> is stopped for specific amount of time during handover procedure. This paper also addresses the situation when it might be necessary to limit the number of UEs in a cell.(More)
