1. A system to provide wireless service comprising:
a baseband unit; and
a radio point;
wherein the radio point is associated with at least one antenna, wherein the radio point is communicatively coupled to the baseband unit;
wherein the baseband unit and the radio point are configured to implement at least one base station in order to provide wireless service via a wireless interface to a plurality of user equipment (UEs) using at least one cell;
wherein the system is configured so that physical layer processing for the wireless interface is split so that some of the physical layer processing is performed in the baseband unit and some of the physical layer processing is performed in the radio point; and
wherein the system is configured so that scrambling of first downlink data to be communicated to a UE over the wireless interface is performed in the baseband unit and so that scrambling of second downlink data to be communicated to said UE over the wireless interface is performed in the radio point.
