Abstract: An echo-canceling unit for a simultaneous transmit and receive (STR) system includes at least three phase shifters instead of just two phase shifters in order to provide immunity to phase and/or amplitude imbalances. Each respective phase shifter is coupled to a transmit signal to generate an output signal comprising a selected phase shift with respect to the transmit signal. A weight calculation unit generates a corresponding amplitude-weight signal for the output signal of the phase shifter. A variable attenuator attenuates the output signal of each respective phase shifter based on the corresponding amplitude-weight signal to form an echo-cancelation signal component corresponding to the phase shifter. A first summer then sums the respective echo-cancelation signal components into a received signal containing an echo signal to form an echo-canceled signal. In some embodiments, an information handling system includes a receiver and a transmitter coupled to the echo-canceling unit.

Abstract: A multi-stage adaptive filter is disclosed, which exhibits a smaller mean square error than in prior art adaptive filters. The adaptive filter selectively manipulates the weights, in multiple stages, so as to achieve a global minimum of the error function, such that the filtered signal has as small an error as possible.

Abstract: A method and an information handling system configured to select a mobility anchor point for a mobile device in a distributed mobility anchor point network may comprise collecting information about movement behavior or data transfer behavior of the mobile device, or tunneling overhead of two or more base stations. A mobility anchor point associated with a first base station may be assigned to the mobile device if the mobile device is connected to the first base station for at least a predetermined amount of time, if the mobile device transfers at least a predetermined amount of data via the first base station, or device if a tunneling overhead of the first base station is less than a predetermined level.

Abstract: Aspects of the subject disclosure may include, for example, a device, process or software that determines an operation between a number of pairs of antennas of a set of antennas. A pair of antennas of the number of pairs of antennas is determined based on the operation. One antenna of the pair of antennas is eliminated from the set of antennas, which results in a reduced number of antennas remaining in the set of antennas. Each of the determining of the operation, the determining of the pair of antennas of the reduced number of antennas and the eliminating of the one antenna of the pair of antennas is repeated in response to the reduced number of antennas being greater than a predetermined number of antennas. Other embodiments are disclosed.

A first computing device may establish with a second computing device a full-duplex communication channel that may have a forward data transmission direction and a reverse data transmission direction. The first computing device may transmit to the second computing device a first data portion in the forward data transmission direction of the full-duplex communication channel at a default data transmission rate. The first computing device may receive a second data portion in the reverse direction of the full-duplex communication channel that may contain a forward channel quality information (CQI) associated with the forward data transmission direction.

A downlink transmission and an uplink receive beam are formed at a base station (BS) having a beam pattern with predetermined nulls. The predetermined nulls are formed over predetermined elevation angles to reduce interference with a proximate BS. Transmission and reception occur simultaneously using the beam pattern from the BS.

Abstract: Examples are disclosed for simultaneous transmitting and receiving packets in a wireless local access network (WLAN). In some examples, a source node in the WLAN may transmit a packet to a destination node in the WLAN and may receive an implicit acknowledgement (ACK) packet from the destination node. The source node may stop transmitting a remaining portion of the packet if the implicit ACK packet is not received within a defined time interval or if a dummy/packet payload for the implicit ACK packet is not successfully decoded. Also, the destination node may or may not include a data payload in an implicit ACK packet sent responsive to receiving the packet from the source node. Other examples are described and claimed.

Abstract: Wireless-device-to-wireless device (WD-WD) interference in a full-duplex wireless network is managed by an uplink transmit power control technique that minimizes interference experienced in downlink signals at other wireless devices in the wireless network. In one exemplary embodiment, an instantaneous antenna gain of the wireless device and a target uplink Signal-to-Interference-plus-Noise Ratio (SINR) of an uplink signal of the wireless device to the home base station are determined at the wireless device. A Noise plus Interference level at the home base station is received by either a closed-loop or an open-loop feedback technique. The uplink power level for an uplink signal of the wireless device is determined based on the determined antenna gain, the determined target uplink SINR and the received Noise plus Interference level at the home base station.

Abstract: A simultaneous transmit and receive (STR) technology is described. The eNB is configured with a downlink centric measurement threshold and an uplink centric measurement threshold which increase overall capacity in the wireless cellular network. A signal measurement command is transmitted from the eNB to the UE instructing the UE to take a signal quality measurement. The signal quality measurement is received from the UE at the eNB. It is determined whether the signal quality measurement is greater than the downlink centric measurement threshold and whether the signal quality measurement is greater than the uplink centric measurement threshold.
