A vectoring controller for configuring a vectoring processor that jointly processes DMT communication signals to be transmitted over, or received from, a plurality of N subscriber lines according to a vectoring matrix. In accordance with an embodiment, the vectoring controller is configured, for given ones of a plurality of tones, to enable the given tone for direct data communication over a first set of NMk targeted lines out of the plurality of N subscriber lines, and to disable the given tone for direct data communication over a second disjoint set of Mk supporting lines out of the plurality of N subscriber lines, Mk denoting a non-null positive integer. The vectoring controller is further configured to configure the vectoring matrix to use an available transmit or receive power at the given tone over the second set of Mk supporting lines for further enhancement of data signal gains at the given tone over the first set of NMk targeted lines.

The antenna can receive a plurality of DSSS signals from other nodes on a particular channel, and output a channel that includes the plurality of DSSS signals. The plurality of DSSS signals include transmissions that are directly received from other nodes and multi-path components of those transmissions. The receiver processing chain can include a multi-user RAKE receiver that can combine, when performing demodulation processing, a plurality of transmissions directly received from the other nodes and multipath components of transmissions received from the other nodes. In some implementations, the node can perform cooperative beamforming and adaptive space-spectrum whitening.

A node is provided for a cooperative broadcast multi-hop network that employs broadcast flood routing and multi-hop transmission. The node includes antennas and a waveform module having a receiver processing chain that can include an adaptive space-spectrum whitener (ASSW) module and a multi-user RAKE (mRAKE) receiver. Each antenna can receive output a channel that includes direct-sequence spread-spectrum signals received from other nodes and multi-path components of those transmissions. The ASSW module can perform adaptive space-spectrum whitening to detect and remove interference signals received from each of the channels by performing a covariance analysis to generate channelized signals. The ASSW module can include modified Discrete Fourier Transform (MDFT) analysis and synthesis modules that generate an interference mitigated time-domain channelized signals. The mRAKE receiver, when performing demodulation processing, can combine the interference mitigated time-domain channelized signals to generate fingers that combine components of transmissions received from the other nodes.

Systems, devices, and configurations to implement trusted connections within wireless networks and associated devices and systems are generally disclosed herein. In some examples, a wireless local area network (WLAN) may be attached to a 3GPP evolved packet core (EPC) as a trusted access network, without use of an evolved packet data gateway (ePDG) and overhead from related tunneling and encryption. Information to create the trusted attachment between a mobile device and a WLAN may be exchanged using Access Network Query Protocol (ANQP) extensions defined by IEEE standard 802.11u-2011, or using other protocols or standards such as DHCP or EAP. A trusted WLAN container with defined data structure fields may be transferred in the ANQP elements to exchange information used in the establishment and operation of the trusted attachment.

A transmitter for transmitting data to a receiver of a wireless communication network, the transmitter includes at least one antenna, a codebook, an encoder, and a transceiver coupled to the encoder and to the at least one antenna. The codebook includes a plurality of codewords, each codeword being a vector including a plurality of symbols, each symbol to be transmitted over resources of the wireless communication network. The encoder is configured to receive an information message to be transmitted to a receiver of the wireless communication network, to select from the codebook the codeword associated with the received information message, and to divide the selected codeword into a plurality of sub-codewords. The transceiver is configured to transmit via the at least one antenna a first sub-codeword, and to transmit via the at least one antenna a second sub-codeword responsive to an indication that the encoded information message was not successfully decoded at the receiver on the basis of the received first sub-codeword.

Wireless communication devices are adapted to facilitate transmission and reception of non-orthogonal communications. In one example, wireless communication devices can encode an amount of data in accordance with information that at least some of the data will be transmitted as part of a non-orthogonal transmission. The wireless communication device may further transmit the encoded data, and the encoded data can be non-orthogonally combined as part of a non-orthogonal transmission. In another example, wireless communication devices can receive a wireless transmission including a plurality of data streams non-orthogonally combined together.

Channel estimates are determined for the plurality of wireless users. The first and second antenna data is jointly processed. Interference from the wireless user connected via a third antenna is suppressed based on a determined corresponding channel estimate for the wireless user and other received information for the wireless user.

Methods and devices for assigning sounding reference signals (SRS) resources to UEs in a wireless communication network are provided. Configuration information is sent to a UE, the configuration information pertaining to a first sequence identifier (ID) to be used by the UE to generate a plurality of SRS sequences to be sent by the UE as at least part of a first SRS. Each SRS sequence of the plurality of SRS sequences is a function of a respective SRS sequence root that is a function of the first sequence ID.
