摘要： Wireless protocols in the unlicensed spectrum are developed for different requirements in terms of transmit range and power, which makes it difficult for multiple nodes having disparate transmit ranges to coexist in the same unlicensed spectrum. A short-range wireless node uses adaptive preambles to signal presence to long-range wireless nodes outside of its transmit range. In addition, a long-range wireless node detects an adapter preamble and backs-off transmissions for reservation period dedicated to short-range nodes.

摘要： Full-duplex wireless communication is described. In an embodiment, a transceiver device having a transmitter circuit and a receiver circuit receives a data packet sent over a shared communication medium. In the embodiment, the transceiver reads the header of the data packet and starts transmitting an output signal on the same shared communication medium. Embodiments are described in which, whilst the transmission of the output signal is ongoing, the transceiver receives an impaired data signal which is made up of the payload of the data packet and interference from the output signal. In the embodiment, a cancellation signal is derived from the output signal, and this is combined with the impaired data signal to remove the interference and recover the payload of the data packet.

摘要： Dynamic channel and transmission rate selection is described. In an example, a communication resource for transmitting data to a receiver is selected from several channels, each having several associated rates. The selection comprises storing a weighting factor for each channel/rate combination, monitoring transmission performance on a selected channel and rate, and inferring performance for other rates on the selected channel from the monitored performance. Each weighting factor is then updated using the monitored and inferred performances, and used to select a channel/rate combination for subsequent transmission. In another example, a communication device comprises a transmitter, a processor, and a memory arranged to store a weighting factor associated with each receiver, channel and rate combination. The transmitter sends data to a receiver using one channel and rate, and the processor monitors the performance, updates the weighting factors accordingly, and selects a receiver, channel and rate combination for subsequent transmission.

摘要： A resource allocation framework for wireless/wired networks is described. In an embodiment, methods of end host based traffic management are described which operate separately from the underlying access control protocol within the network (e.g. wireless MAC protocol or TCP). The rate limits for each flow are set based on per-flow weights, which may be user specified, and based on an estimate of the utilization of the shared resource and the rate limits are adjusted periodically so that the resource is not underutilized or saturated. Some embodiments compute a virtual capacity of the resource which is adjusted to optimize the value of the utilization and then the virtual capacity is shared between flows according to the per-flow weights. Methods for estimating the utilization of a wireless network and the capacity of a broadband access link are also described.
