However, it should be once more noted at this point that such data rates can only be achieved by very few users of a cell. Details are given in Chapter 3. As uplink transmissions are usually power limited, MIMO has only been considered for the downlink direction. 3 Continuous Packet Connectivity Continuous Packet Connectivity (CPC) is a package of features introduced in the 3GPP standards to improve handling of mobile subscribers while they have a packet connection Beyond 3G Network Architectures 39 established, that is while they have an IP address assigned.
The Fractional-DPCH feature puts the RRC messages on the HSDPA shared channels and the mobile thus only has to decode the power control information from the DPCH. At all other times, that is when the terminal is not in HSDPA active mode, the DPCH is not used by the mobile (thus it is fractional). During these times, power control information is transmitted for other mobiles using the same spreading code. Consequently, several mobiles use the same spreading code for the dedicated physical channel but listen to it at different times.
For instance, there are a number of initiatives in Release 7 and Release 8 of the 3GPP standard to further improve the system. Improvements of the air interface are referred to as HSPAþ. In addition, the network architecture has also received an optional overhaul to be more efficient with a feature referred to as ‘one-tunnel’. The following section gives an overview of these improvements, many of which are likely to be introduced into networks over the next few years.
