Abstract
Example embodiments are directed to methods of reducing inter-cell interference in wireless networks using successive interference cancellation (SIC). Example embodiments use inter-cell cooperation between cells and/or sectors to successfully decode their associated users' data signals and pass on the decoded data signals to other cells/sectors in order to reduce inter-cell interference and allow for improved decoding of users' data signals. Example embodiments include passing the decoded data signals via the backhaul. Example embodiments also include static and dynamic ordering of user data signals in conjunction with the application of SIC.
