Remote radio unit using adaptive compression in a distributed radio access network
A distributed radio frequency communication system includes a remote radio unit (RRU and a baseband unit (BBU) and facilitates communication between a wireless terminal and a core network. The RRU receives a radio frequency signal from a wireless terminal and convert the radio frequency signal to digital baseband samples using receiver circuitry and an analog-to-digital converter. The RRU then adaptively compresses the digital baseband samples, using adaptive compression circuitry, to create fronthaul uplink information, and sends the fronthaul uplink information over a fronthaul link to the BBU using an adaptive fronthaul protocol. The RRU also receives fronthaul downlink information over a fronthaul link from the BBU using an adaptive fronthaul protocol and generates frequency-domain samples, based on the fronthaul downlink information received. It then creates time-domain baseband samples from the frequency-domain samples and converts the time-domain baseband samples into a radio frequency signal to send to the wireless terminal.

APPARATUS, SYSTEM, AND METHOD FOR PACKET SWITCHING
An apparatus is provided for control of a plurality of forwarding switches using a network controller. The network controller executes a routing configuration application that analyzes interconnections between the forwarding switches to identify a topology of the network, determine label switched paths (LSPs) between the forwarding switches, and transmits the next hop routes to the forwarding switches.

Each LSP includes one or more next hop routes defining a forwarding address associated with one forwarding switch to an adjacent forwarding switch.
Beamforming feedback tone/sub-carrier location within wireless communications
A wireless communication device (alternatively, device, WDEV, etc.) includes at least one processing circuitry configured to support communications with other WDEV(s) and to generate and process signals for such communications. In some examples, the device includes a communication interface and a processing circuitry, among other possible circuitries, components, elements, etc. to support communications with other WDEV(s) and to generate and process signals for such communications.
