1. A method comprising:

  • in a wireless communication device that implements radio frame equalization in compliance with a telecommunications standard that specifies a transmission time interval to be 10*2N ms, N being any integer ranging from 0 to 3,storing a block of channel encoded data of a transport channel in a memory comprising memory lines each having 8 bits;

    if the block of channel encoded data has a number of bits that is not an integer multiple of 8, storing one or more padded bits after an end of the block of channel encoded data to an end of a last memory line occupied by the block of channel encoded data;

    reading the block of channel encoded data and the padded bits from the memory in equal sized segments;

    wherein a group of registers is provided to store time slot configuration parameters includes writing five sets of time slot configuration parameters for configuring a chip rate processing unit to process five uplink time slots of a sub-frame; and

    processing data using the chip rate processing unit, including performing at least one of spreading data, scrambling data, and combining data from multiple physical channels to prepare the data for uplink transmission;

    wherein the telecommunications standard comprises Time Division-Synchronous Code Division Multiple Access standard.
