Method and apparatus for reducing interference in a wireless communication system when the source of interference is a deterministic component of the system. In one embodiment, the receiver weights the transmitters according to when the source of interference is transmitted. Further, the transmitter may employ power boosting to overcome the source of interference. In one embodiment, a W-CDMA system transmits a sync channel concurrently with physical channels, wherein the sync channel is not orthogonal to the physical channels. The receiver may cancel the sync channel when receiving control or data information. Similarly, the receiver may weight the transmissions from multiple transmitters.

What is claimed is: 1. A method in a wireless communication system, comprising: formatting messages for transmission in frames having a plurality of slots, wherein each frame has a first number of slots; dividing each frame into a second number of portions, wherein the second number of portions is not a multiple of the first number of slots; interleaving the plurality of slots in each frame using the second number of portions; and transmitting an interleaved frame. 2. The method as in claim 1, wherein the wireless communication system is a Wideband-Code Division-Multiple Access (W-CDMA) system. 3. The method as in claim 1, wherein the interleaving comprises block interleaving. 4. The method as in claim 1, wherein the second number of portions is a dynamic number varying over time. 5. An apparatus in a wireless communication system, comprising: means for formatting messages for transmission in frames having a plurality of slots, wherein each frame has a first number of slots; means for dividing each frame into a second number of portions, wherein the second number of portions is not a multiple of the first number of slots; means for interleaving the plurality of slots in each frame using the second number of portions; and means for transmitting an interleaved frame. 6. An apparatus in a wireless communication system, comprising: transmitter, and processor adapted to: format messages for transmission in frames having a plurality of slots, wherein each frame has a first number of slots; divide each frame into a second number of portions, wherein the second number of portions is not a multiple of the first number of slots; interleave the plurality of slots in each frame using the second number of portions; and transmit an interleaved frame. 7. An interleaver, comprising: means for dividing a transmission frame having a first number of slots into a second number of portions, wherein the second number of portions is not a multiple of the first number of slots; and means for interleaving the first number of slots using the second number of portions. 8. A method in a wireless communication system, comprising: formatting messages for transmission in frames having a plurality of slots; dividing each frame into a predetermined number of portions; interleaving the plurality of slots in each frame, wherein the bits of each slot are reversed; and transmitting an interleaved transmission. 9. An apparatus in a wireless communication system, comprising: means for formatting messages for transmission in frames having a plurality of slots; means for dividing each frame into a predetermined number of portions; means for interleaving the plurality of slots in each frame, wherein the bits of each slot are reversed; and means for transmitting an interleaved frame. 10. An apparatus in a wireless communication system, comprising: transmitter; and processor adapted to: format messages for transmission in frames having a plurality of slots; divide each frame into a predetermined number of portions; interleave the plurality of slots in each frame, wherein the bits of each slot are reversed; and transmit an interleaved frame.
