Abstract: Technology is discussed to allow transmission points within a Wireless Wide Area Network (WWAN) to adapt to Up Link (UL) and Down Link (DL) traffic demands independently. To mitigate potential interference arising from transmission points scheduled for conflicting UL and DL transmissions, measurements between transmission points can be made to indicate a level of coupling. Based on the various levels of coupling between transmission points, clusters can be formed. Where a high level of coupling is present, transmission points can be included in a common cluster. Where a low level of coupling is present, they can be isolated. Transmission points within the same cluster are scheduled with a common pattern of UL and DL transmissions to avoid interference. Transmission points in different clusters can have different patterns of UL and DL transmission to independently adapt to the relative demands for UL and DL transmissions experienced within these different clusters.

Abstract: In a wireless, OFDM system, phase noise may be mitigated through the use of an interleaver that is designed to distribute coded block bits across subcarriers of multiple OFDM symbols. Doing so decreases the non-stationary properties of the noise. Such an interleaver may be a rectangular interleaver that maps each block to a different subcarrier to create frequency diversity and to a different OFDM symbol, to create time diversity. One exemplary method of interleaving the symbols is to place a first symbol at row X and column Y of the interleaver. The next symbol is placed in row X+1 and column Y+1. The result of such an interleaving process is a great reduction in the block error rate.
