    摘要： An echo-canceling unit for a simultaneous transmit and receive (STR) system includes at least three phase shifters in which 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.

    摘要： 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.

    摘要： 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. In some embodiments, a centralized mobility anchor may be assigned to the mobile device if the mobile device is highly mobile and there is no identified base station to which the mobile device is frequently connected.
