A wireless system has an uplink chip rate processing architecture in which at least two groups of registers are provided, each group of register storing a set of time slot configuration parameters. A storage stores a sequence of time slot configuration set identifiers each identifying one of the groups of registers, each identifier corresponding to a time slot. A chip rate processing unit processes a stream of data over a plurality of time slots in which at each of the time slots, and the chip rate processing unit is configured according to the set oftime slot configuration parameters stored in the group of register associated with the time slot configuration set identifier corresponding to the time slot.
