Abstract: Methods and apparatus that enable one or more wireless networks to minimize inter-cellular interference (ICI) at a receiver. In one embodiment, the network comprises an OFDM-based cellular network, and the method comprises utilizing a priori knowledge of non-data portions of signals from multiple base stations in order to schedule transmissions. In one variant, these non-data portions comprise pilot tones; the pilot tones can be scheduled onto various time-frequency resources of the network so as to minimize ICI. The mobility context of the receiver can also be used as a basis for dynamically adjusting the pilot tone density. In another variant, precoding (e.g., Tomlinson-Harashima precoding) can be applied to “shape” the non-data portions of the transmitted signals so as to mitigate ICI. In yet other variants, frame preambles and learning sequences are used as the basis for invoking selective transmission time shifts across the potentially interfering base stations so as to minimize ICI.

Abstract: Methods and apparatus that enable and optimize the simultaneous operation of several wireless femtocells having overlapping coverage areas. In one embodiment of the invention, a resource allocation (e.g., time-frequency grid for an OFDM or TDMA based wireless network) governs the simultaneous operation of several femtocells with overlapping coverage areas by specifying uses for resources. A resource allocation unit (RAU) entity is disclosed for managing and modifying resource allocations for femtocells. The community of femtocells can flexibly share resources according to the time-frequency grid, thereby maximizing spectral efficiency without requiring substantial network overhead.

Abstract: Methods and apparatus that seek to increase the diversity seen in wireless communication systems by intelligently implementing a joint multi-dimensional permutation approach. In an exemplary embodiment, this is accomplished by combining the permutation of various transmitter antennas, various data streams (for example, in a MIMO configuration) and various constellation-bit mappings into a coherent multi-dimensional permutation scheme. Subsequent retransmissions in combination with an initial transmission are utilized to obtain substantial signal flattening at a receiver which increases the likelihood that retransmissions that follow detected errors will successfully convey the transmitted data to the receiver. Both open and closed-loop approaches are contemplated which take advantage of the multi-dimensional permutation schemes. In addition, embodiments utilized in the context of retransmission mechanisms such as HARQ are also contemplated.
