  • Patent number: 10749787
    Abstract: Described embodiments provide systems and methods for path selection proportional to a penalty delay in processing packets. A server-side intermediary may identify a delay penalty for processing packets of a server destined for a client. The server-side intermediary may be in communication via links of different latencies with a client-side intermediary. The server-side intermediary may select a second link with a latency that deviates from the lowest latency of a first link by the delay penalty. The server-side intermediary may transmit, to the client-side intermediary, duplicates of the packets via the selected second link with information indicating to hold the duplicates at the client-side intermediary. The server-side intermediary may receive an indication to drop or send the duplicates to the client. The server-side intermediary may transmit the indication to the client-side intermediary to drop or send the duplicates according to the indication.

  • Patent number: 10716127
    Abstract: Various solutions with respect to uplink control information (UCI) feedback timing signaling in wireless communications are described. A user equipment (UE) identifies a type of uplink (UL) transmission to perform with respect to a network node of a wireless network. The UE receives a control signal from the network node and determines, based on the control signal, a timing offset of a transmission schedule for the identified type of the UL transmission. The UE performs the UL transmission to the network node according to the transmission schedule such that a first type of the UL transmission is performed with a first timing offset and a second type of the UL transmission is performed with a second timing offset different than the first timing offset.
