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: A method operates to transmit a data signal by a transmission unit of a wireless multiple-input/multiple-output (MIMO) communication system. The communication system includes the transmission unit and a reception unit, the transmission unit having a plurality of transmission antennas and the reception unit having a plurality of reception antennas. The method includes performing a first transmission of a data signal, the first transmission including transmitting the data signal by each one of the plurality of transmission antennas, and performing a second transmission of the data signal at a time later than the first transmission, the second transmission including transmitting at least one spectrally modified signal variant of the data signal by at least one antenna of the plurality of transmission antennas.

Abstract: One embodiment of the present invention relates to a method for efficient reassignment of a secondary communication channel (having a first priority) within a white space, upon arrival of a conflicting primary user signal (having a second priority higher than the first priority). In particular, the method comprises reassigning a secondary communication channel to unused portions of one or more white spaces remaining after the arrival of one or more primary users. For example, in one embodiment wherein one or more secondary communication channels are operated at contiguous secondary frequency ranges within a white space, a primary/incumbent user may arrive at a frequency range that conflicts with the secondary frequency range and that generates unused frequency portions of the white space(s). The secondary communication channel may be reassigned to the unused frequency portions of the white space (e.g.

Abstract: Methods and apparatus enabling a wireless network to generate data that can be used by a receiver (e.g., UE) to resolve the contributions of individual transmitters, such as to determine its location without resort to external devices such as GPS satellites. In one embodiment, the wireless network comprises a single frequency network (SFN), and a unique base station identifier is embedded within the data, and encoded in a manner which allows the UE to calculate path characteristics (such as path latency, and Direction of Arrival) to triangulate its position. In one variant, the data encoding comprises weighting frames of data from different base stations using an orthogonal matrix. Advantageously, the encoding and embedded identifier are also transparent to legacy UE, thereby allowing for implementation with no infrastructure or UE modifications other than software. Network and user apparatus implementing these methodologies, and methods of doing business, are also disclosed.

Abstract: Methods and apparatus to enable a wireless network system to dynamically change information channel message broadcasts. In one aspect, cellular network systems optimize pilot channel message delivery based at least in part on one or more network parameters. Base stations and/or cellular devices can dynamically configure the pilot channel message delivery or reception based on the network parameters. For example, such flexible pilot channel message delivery may more frequently deliver prioritized pilot channel messages, and less frequently broadcast low priority messages. Cellular subscribers with appropriately enabled user equipment may improve their power and applications performance through implementation of the invention. Furthermore, base stations may reclaim the freed cellular resources to support other services. Legacy subscribers are advantageously not affected.

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.
