摘要： For transmission of a block of control information within a wireless network, the control information is interleaved to form an ordered set of control bits, wherein more important information bits of the control information are placed into a first portion of the ordered set of control bits, with less important information bits of the control information placed into a second portion of the ordered set of controls bits. The ordered set of control bits is encoded to form an encoded block of data. The encoded block of data is transmitted to a serving base station, wherein bits from the first portion of the ordered set of control bits will statistically have a lower bit error rate (BER) than bits from the second portion of the ordered set of control bits during transmission.
