A boundary of a wireless network is monitored for incoming wireless signals that may interfere with an ability of a first wireless computing device to connect to the wireless network within the boundary of the wireless network. For an incoming wireless signal determined to interfere with the ability of the first wireless computing device to connect to the wireless network within the boundary of the wireless network, a directional opposing outgoing wireless signal is emitted to counteract the incoming wireless signal and to stop the incoming wireless signal from further interfering with the ability of the first wireless computing device to connect to the wireless network within the boundary of the wireless network.

Method of scrambling signals, transmission point device, and user equipment using the method are provided. The method includes: sending an ID table to a user equipment through higher layer signaling, the ID table being a subset of the whole ID space and containing available IDs for the user equipment; notifying the user equipment an ID in the ID table to be used through physical layer signaling or UE specific higher layer signaling; generating a random seed based on the notified ID; initializing a scrambling sequence by the random seed; and scrambling the signals with the initialized scrambling sequence. The method of the disclosure, by combining physical layer signaling and higher layer signaling, may notify the used group ID and the blind detection space to a UE, wherein the blind detection for the UE is enabled and the signaling overhead is reduced.

A transceiver for providing full-duplex communications includes a multilevel patch antenna array having a first patch antenna array for transmitting the first carrier signal on the first channel including a first plurality of patch antennas thereon and a second patch antenna array for receiving the second carrier signal on the second channel including a second plurality of patch antennas thereon. Transmitter circuitry associated with the first patch antenna array transmits first signals having a first orthogonal function applied thereto on a first channel on a first frequency band. Receiver circuitry associated with the second patch antenna array receives remotely transmitted second signals on a second channel on the first frequency band having a second orthogonal function applied thereto and the first signals transmitted from the first patch antenna array having the first orthogonal function applied thereto on the first channel on the first frequency band at a same time on the first frequency band. The receiver circuitry only processes received signals including the second orthogonal function. The first orthogonal function applied to the first signals transmitted from the first antenna array and the second orthogonal function applied to the second signals prevents interference between the first signals and the second signals that are being simultaneously transmitted and received on the first frequency band at the multilevel patch antenna array.

In this terminal apparatus: a pilot information deciding unit decides, based on allocation control information, Walsh sequences of the respective ones of first and second stream groups at least one of which includes a plurality of streams; and a pilot signal generating unit forms a transport signal by using the decided Walsh sequences to spread the streams included in the first and second stream groups. During this, Walsh sequences orthogonal to each other are established in the first and second stream groups, and users are allocated on a stream group-by-stream group basis.

A multiple access scheme is provided. A first communications terminal encodes a first data stream using a forward error correction (FEC) code, and scrambles the encoded first data stream based on a first scrambling signature. A second communications terminal encodes a second data stream using the FEC code, and scrambles the encoded second data stream based on a second scrambling signature. The first scrambling signature and the second scrambling signature are used, respectively, by the first terminal and the second terminal to distinguish the first encoded data stream from the second encoded data stream as respectively originating from the first terminal and the second terminal in a multiple access scheme, whereby the first encoded data stream and the second encoded data stream simultaneously share a wireless communications channel. The FEC code is a low density parity check (LDPC) code configured with a data node degree of two or three.

A system and method for reducing the OFDM out-of-band emissions (OOBE) by utilizing a transmitter windowing operation that smooths the inherent rectangular pulse shape of the OFDM signals. The technique retains the main design of the OFDM receivers and provides backward compatibility for the existing OFDM-based systems. The guard band and the window parameters that control the guard duration are jointly optimized regarding the use case and the power offset between the users. To fully exploit and further increase the potential of adaptive guards, an interference-based scheduling algorithm is proposed as well.
