Method and apparatus for reducing inter-channel interference in a wireless communication system
First Claim
1. A method in a wireless communication system, comprising:
- determining a slot location of a message on a non-orthogonal channel;
assigning a weight to a plurality of transmitters as a function of Signal-to-Noise Ratio (SNR) as received at a receiver; and
decoding transmissions received at the receiver from each of the plurality of transmitters, wherein during the slot location the decoding is according to the assigned weights.

Abstract
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.
