The chapter concentrates on the changeover of some RRM features including the packet scheduler into NodeB. The modifications in RRM functions from the network nodes triggered additional modifications of HSDPA air interface including introduction of greater‐order modulation and coding techniques, and modification on the MAC protocol architecture for enabling the fast scheduling during the BTS.

System-stage simulation benefits within the HSDPA overall performance are offered to expose the effects of user products (UE) capabilities like the most quantity of multicodes and obtain variety and point out that reduction of your spherical vacation time, the next uplink data rate, and low uplink block mistake rate are needed to achieve the higher TCP-degree throughput.
Whenever a mobile is idle, it is usually listening to a paging channel. The moment a mobile has parsed each of the network overhead information and facts, it registers with the network, then optionally enters slotted-mode. Each of these procedures are explained in additional element below.
