摘要:
Methods and systems are described for causing orthogonal frequency division multiplexing (OFDM) transmission of various portions of data via various nodes. For example, a first portion of the data may be transmitted, via a first node and using OFDM, to at least a second node. It may be determined that a second portion of the data is to be routed via a different node (such as a third node) for transmission. The second portion of the data may be transmitted, via the third node and using OFDM, to at least the second node.

An apparatus for generating at least one signal based on at least one aspect of at least two received signals is provided. The apparatus comprises: a diverse antennae array of M antennae, where M is greater than or equal to two; at least one multiple-input and multiple-output capable transceiver in communication with each antenna in the diverse antennae array of M antennae; encoding circuitry capable of causing first data to be encoded; decoding circuitry capable of causing second data to be decoded; and processing capable of causing diversity combining, where the processing circuitry is in communication with the multiple-input and multiple-output capable transceiver, the encoding circuitry, and the decoding circuitry. In operation, the processing circuitry is capable of causing the apparatus to: receive at least two first signals, combine at least two of the at least first two signals, generate at least two second signals based on at least one aspect of the at least two first signals, and simultaneously transmit the at least two second signals. Additionally, the apparatus is configured such that at least one of the at least two second signals is capable of being received by a multiple-input capable node.

An apparatus for modulating transmit data and adding a cyclic prefix to the transmit data is provided. The apparatus comprises: transceiver hardware that is capable of receiving receive data utilizing multiple input channels and includes at least one first wireless element that is orthogonal frequency division multiplexing-capable, and at least one second wireless element; and circuitry capable of working in association with the transceiver hardware. In operation, the apparatus is configured so as to cause transmission of at least one transmit signal including at least a portion of the transmit data to a node. The apparatus is further configured so as to allow adaptive routing utilizing another route different from a previous route. In addition, the apparatus is configured such that the adaptive routing includes allowing routing as a function of a link quality associated with at least one link.

Methods and systems are described for transmitting data to a node using a plurality of radio frequency channels. The data may be allocated, based on feedback from the node, into various portions amongst multiple radio frequency channels and/or amongst tones associated with the radio frequency channels. The data portions may be transmitted to the node, using frequency diversity, via respective radio frequency channels as at least part of respective orthogonal frequency division multiplexing (OFDM) transmissions, which may be at least partially concurrent transmissions.

Methods and systems are described for causing orthogonal frequency division multiplexing (OFDM) transmission of various portions of data via various nodes. For example, a first portion of the data may be transmitted, via a first node and using OFDM, to at least a second node. Based on one or more observed capacities associated with one or more nodes (such as the first node and/or another node), it may be determined that a second portion of the data is to be routed via a different node (such as a third node) for transmission. The second portion of the data may be transmitted, via the third node and using OFDM, to at least the second node.

Methods and systems are described for determining and transmitting at least one orthogonal frequency division multiplexing (OFDM) symbol that may comprise data associated with multiple nodes such as a first node and a second node. Each OFDM symbol may be determined using weights, time-frequency channels, and/or tones that are determined based at least in part on transmissions from the first node and the second node.
摘要:
Methods and systems are described for orthogonal frequency division multiplexing (OFDM) transmission of data associated with multiple nodes and/or users. A plurality of weights may be determined based on, for example, feedback from one or more nodes. The feedback from each node may be indicative of weighting information. A multiple-input multiple-output (MIMO)-capable node may transmit OFDM transmissions, which may be time and frequency coincident, using the plurality of weights. For example, the MIMO-capable node may transmit a first OFDM transmission using at least a first weight of the plurality of weights and a second OFDM transmission using at least a second weight of the plurality of weights. This may allow the MIMO-capable node to, for example, transmit OFDM transmissions to multiple users via one or more common time-frequency channels.

The first node may transmit the signal as an orthogonal frequency division multiplexing (OFDM) transmission.
摘要:
Methods and systems are described for determining a plurality of transmission levels for, e.g., a plurality of time-frequency channels and/or a plurality of tones. The transmission levels may be determined by a first node based on, for example, a received transmission from a second node. The first node may generate a signal, which may be based on, for example, an originator-based pseudorandom sequence, a recipient-based pseudorandom sequence, and/or a complex sinusoid. The first node may transmit the signal as an orthogonal frequency division multiplexing (OFDM) transmission.
