The chapter focuses on the changeover of some RRM features including the packet scheduler into NodeB. The modifications in RRM functions of the network nodes brought about extra modifications of HSDPA air interface together with introduction of better‐purchase modulation and coding strategies, and modification on the MAC protocol architecture for enabling the fast scheduling inside the BTS.
DSSS is Immediate Sequence Spread Spectrum Procedure and that is a spread spectrum approach wherein the data being transmitted is encoded using spreading code and been given and then decoded using the similar code.
