1. A user equipment (UE) comprising:
a plurality of circuit components to perform initial processing operations on data to be transmitted in an uplink (UL) data transmission from the UE to a base station, wherein the plurality of circuit components include:
a scrambler configured to generate a scrambled sequence based on a scrambling sequence, wherein the scrambling sequence includes a pseudo noise (PN) modulated sequence that is generated based on a PN sequence, wherein the PN sequence is initialized based on a UE identifier and a constant Δ, wherein the constant Δ is predefined or configured based on a minimum system information (MSI) or configured based on a remaining minimum system information (RMSI);
a modulating circuitry coupled to the scrambler to receive the scrambled sequence, and configured to generate modulated symbols based on the scrambled sequence;
a spreader coupled to the modulating circuitry and configured to spread the modulated symbols to generate spread modulated symbols; and
an interleaver, coupled to the spreader to receive the spread modulated symbols, and configured to generate an interleaved sequence based on the spread modulated symbols.
