A communication method includes obtaining, by a source remote direct memory access (RDMA) network interface card (RNIC), to-be-transmitted data sent by a source virtual RNIC (vRNIC), obtaining, by the source RNIC, identity indication information of a destination vRNIC and packet forwarding information, and encapsulating, by the source RNIC, the to-be-transmitted data to obtain a target packet, and sending the target packet to a destination RNIC, where the destination vRNIC is a vRNIC running on the destination RNIC.

A network state is verified in real-time by precomputing a data structure representing header spaces of data packets in respective equivalence classes (ECs) in a first snapshot of the network and in a second snapshot of the network at a later time. The data structure includes respective bitmaps indicating for each data packet forwarding rule for each node in the network a forwarding action to be taken for each EC in the network. The respective bitmaps store bits indicating for each data packet forwarding rule whether the data packet forwarding rule applies to the respective ECs in the network. The snapshots are compared to identify network paths that have changed between a time of the first snapshot and the second snapshot of the network and network verification operations are performed on the changed network paths as a logical function of a bitmap corresponding to each changed network path.

Embodiments include processes, systems, and devices that allow a white space base station to request available frequency ranges for white space transmission in a local area. A white space finder service models a primary user device's transmission signal propagation area using terrain data associated with the local area of the primary user device. The white space finder service also determines, based on the location of the white space base station and the modeled propagation area, one or more locally available, non-interfering frequency ranges and provides them to the white space base station. The white space base station compares the provided frequency ranges to policies and selects one or more of the available frequencies that accommodate the policies. The white space base station also maps the transmission frequency ranges to virtual frequency ranges for transmission by a software-defined radio employing spectrum virtualization.

Spectrum allocation for base station

Implementations for retransmitting erroneous portions within a transmission frame are described. A sender transmits a transmission frame and the receiver performs error detection on portions of the transmission frame in order to determine if any are received in error. The receiver sets up a feedback channel and transmits acknowledgements to the receiver to indicate that one or more portions have been received and to identify any portions that are received with errors. At least some of the acknowledgements are transmitted prior to receipt of the entire transmission frame. The sender retransmits any portions that are identified as being erroneous within the transmission frame.

In-frame acknowledgments and retransmissions

A radio control board exchanges data with a radio frequency (RF) front end using a messaging protocol over an interface that includes separate data and control channels. Training data can also be passed over the interface for tuning the clock phase.

A real-time task may initially be performed by a first thread that is executing on a first core of a multi-core processor. A second thread may be initiated to take over the performance of the real-time task on a second core of the multi-core processor while the first thread is performing the real-time task. The performance of the real-time tasks is then transferred from the first thread to the second thread with the execution of the second thread on the second core to perform the real-time task.

Multiple core real-time task execution

A fine-grained channel access system and method to facilitate fine-grained channel access in a high-data rate wide-band wireless local-area network (WLAN). Embodiments of the system and method divide an entire wireless channel into proper size subchannels commensurate with the physical layer data rate and typical frame size. Once the subchannels are defined, each node on the WLAN contends independently for each of the fine-grained subchannels. A first orthogonal frequency-division multiplexing (OFDM) technique is used to signal an access point on the WLAN that the node desires one or more of the subchannels. A second OFDM technique (which is different from the first OFDM technique) is used for data transmission. Sometimes there is contention between nodes that want the same subchannel. The access point resolves any contention between the nodes using a frequency domain contention technique that includes a frequency domain backoff technique.

Fine-grained channel access in wireless networks

A cooperative phase tracking system allows access points of a wireless network (e.g., a WiFi network) to use a clock or oscillator that may be different or independent from other access points of the same wireless network. As such, the cooperative phase tracking system eliminates a limitation of using a same clock (or oscillator) among the access points and at the same time may allow more access points to be installed for an associated wireless network to serve a larger area. Moreover, the cooperative phase tracking system may attribute intensive computations of relative phase drifts associated with the access points to a dedicated coordinator, thereby alleviating workload of the access points of the wireless network.

Cooperative phase tracking in distributed multiple-input multiple-output system

Embodiments include processes, systems, and devices for reshaping virtual baseband signals for transmission on non-contiguous and variable portions of a physical baseband, such as a white space frequency band. In the transmission path, a spectrum virtualization layer maps a plurality of frequency components derived from a transmission symbol produced by a physical layer protocol to sub-carriers of the allocated physical frequency band. The spectrum virtualization layer then outputs a time-domain signal derived from the mapped frequency components. In the receive path, a time-domain signal received on the physical baseband is reshaped by the virtual spectrum layer in order to recompose a time-domain symbol in the virtual baseband.
