  • Patent number: 9977745
    Abstract: A router requests a reservation for an egress port prior to dequeuing data from an ingress port data queue. A request is also made for the allocation of a buffer. After the reservation is received and a buffer is allocated, the data is copied the ingress port data queue to the buffer, and an identifier of the buffer is enqueued to an identifier queue of the egress port. After the identifier is dequeued, the data is copied from the buffer to an egress data queue of the egress port, and the buffer is released for reallocation. The buffer can be released prior to completion of the data being copied from the buffer. The queues associated with the egress port determine whether their depths equal or exceed a threshold associated with the respective egress queues. If one or more of the depths does equal or exceed the associated threshold, the granting of reservations for the egress port are postponed.

  • Patent number: 9935757
    Abstract: Techniques are disclosed relating to channel quality reporting for full-duplex (FD) wireless communications. In some embodiments an apparatus (e.g., a mobile device) is configured to receive a reference signal in a wireless communication and determine an effective signal to interference plus noise ratio (SINR) for FD communications based on a measured SINR of the reference signal and one or more self-interference cancelation levels. The apparatus may determine the one or more self-interference cancelation levels based on the transmit power of signals transmitted by the apparatus and residual power after SIC. The SIC levels may include both analog and digital SIC levels, which may be separately determined. One or more modulation and coding schemes may be determined based on the effective SINR. In some embodiments, multiple effective SINRs are determined for multiple different transmission modulation orders used by the apparatus.
