  • Patent number: 10425215
    Abstract: Disclosed is a 5G or pre-5G communication system to be provided for supporting a data transmission rate higher than that of a 4G communication system such as LTE. A method for cancelling self-interference in a full-duplex communication system is provided. The method comprises the steps of: cancelling cancellable self-interference components through an analog interference cancellation circuit, and estimating a channel state of an uplink channel and a channel state of a downlink channel on the basis of remaining residual self-interference components; estimating a channel capacity for each of possible beam combinations on the basis of the estimated uplink channel state and downlink channel state; selecting the beam combination having the largest channel capacity from among the possible beam combinations; and cancelling self-interference from a received signal on the basis of the selected beam combination.

  • Publication number: 20190269888
    Abstract: Defining proximal as toward the heart and distal as away from the heart, a sheath includes a proximal opening and multiple fenestrations maintainable in position slightly beyond a site or point of sheath entry into a vessel by way of an anchoring assembly having a set of radially displaceable anchoring elements configured for abutting a superficial vessel wall. The fenestrations and/or anchoring element(s) are arranged obliquely or non-obliquely around peripheral portions of the sheath. The sheath can receive blood from a pumping source at a proximal opening, and channel the blood toward, to, and through the fenestrations. The fenestrations, in combination with the proximal opening, enable the perfusion of blood into the cannulated vessel in a set of distal directions for perfusing a distal tissue or organ. Flow of blood out of fenestrations directs blood distally towards the limb, head, or other distal region, mitigating the risk of or preventing ischemia.
