A method, wireless communication network, and transmitting device that detects that one or more carrier frequencies have crossed a threshold, selects one or more helping transmitting devices to transmit the detected carrier frequencies, transmits the data assigned to the detected carrier frequencies to the selected helping transmitting devices, wherein the selected helping transmitting devices transmit the data over the detected carrier frequencies.
摘要:
Methods and apparatus for the resource-efficient reception of selected segments of system information in receivers. In one embodiment, a wireless device can automatically receive and store segments of pilot channel information, which may be decoded at a later time. By time-shifting the decoding of pilot channel information (or selectively obviating portions thereof based on “intelligent” filtering), the wireless device can reduce the radio and processing burdens for monitoring radio channels. In one variant, the majority of the wireless device can power down for a “snoozing” mode, wherein the device wakes at a later point in order to decode the cached context information data. Various methods for selectively receiving and filtering context information for storage are also disclosed, as well as network apparatus and associated business methods.
摘要:
A method for transmitting 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.
摘要:
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.
摘要:
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 preceding) 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.

In an embodiment, a radio device is provided. The radio device may include a signal transmitter configured to transmit a plurality of signals, the signals being transmitted with different intensities; a response receiver configured to receive a response message to one of the transmitted signals from a radio communication device having received the respective transmitted signal of the plurality of transmitted signals, the response message identifying the received message; and a assessment circuit configured to assess the reachability of the radio communication device from the radio device based on the intensity of the signal to which the radio communication device has responded.

摘要:
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.
